How did Janina manage to continue smuggling without disobeying her father?

Milkweed was written by Jerry Spinelli in 2003. It is basically about an orphan Jewish child who is trying to survive on the streets of Poland during the Holocaust. The child is not old and mature enough to comprehend what is happening in the ghettos of Poland during this tumultuous time period, and the child is not really sure of his own identity. He is eventually introduced to a group of thieves, one of which is Janina, who acts as his guardian.
Conditions in Poland worsen, of course, due to Nazi rule. Deportations are rampant, and the threat of being taken away from the ghettos is very real. It becomes apparent that the Jews are going to be taken away and killed. Due to their seemingly impending doom, Janina’s father, Mr. Milgrom, tells "Misha," as the orphan is called, that when he and Janina smuggle, they need to just run away. Janina and Misha continue to steal food to feed themselves, and they do run away technically, but it turns out that they do so only in search of Janina's father after they discover he is gone from where they were staying. Janina desperately tries to find her father, and Misha loses sight of her in the crowd of people as Janina is running away. Later, Misha sees her thrown into a boxcar by a Nazi, and Misha gets hit with a club and kicked. He also gets shot in the ear.
